| Answer» {tex}{\\frac{1}{{2x}} + \\frac{1}{{3y}} = 2}{/tex} ... (1){tex}\\frac{1}{{3x}} + \\frac{1}{{2y}} = \\frac{{13}}{6}{/tex} ...(2)Let {tex}\\frac{1}{x}{/tex}= p and {tex}\\frac{1}{y}{/tex}= qPutting this in equation (1) and (2), we get{tex}\\frac{p}{2} + \\frac{q}{3} = 2{/tex}\xa0and\xa0{tex}\\;\\frac{p}{3} + \\frac{q}{2} = \\frac{{13}}{6}{/tex}{tex}\\Rightarrow{/tex}\xa03p + 2q = 12 and 6(2p +3q) = 13 (6){tex}\\Rightarrow{/tex}\xa03p + 2q = 12 and 2p + 3q = 13{tex}\\Rightarrow{/tex}\xa03p + 2q - 12 = 0 .................. (3) and2p + 3q - 13 = 0 ................. (4){tex}\\frac{p}{{2( - 13) - 3( - 12)}} = \\frac{q}{{( - 12)2 - ( - 13)3}}{/tex}{tex} = \\frac{1}{{3 \\times 3 - 2 \\times 2}}{/tex}{tex}\\Rightarrow \\frac{p}{{ - 26 + 36}} = \\frac{q}{{ - 24 + 39}} = \\frac{1}{{9 - 4}}{/tex}{tex} \\Rightarrow \\frac{p}{{10}} = \\frac{q}{{15}} = \\frac{1}{5} \\Rightarrow \\frac{p}{{10}} = \\frac{1}{5}\\,{\\text{and}}\\,\\frac{q}{{15}} = \\frac{1}{5}{/tex}{tex}\\Rightarrow{/tex}\xa0p = 2 and q = 3But {tex}\\frac{1}{x}{/tex}\xa0= p and {tex}\\frac{1}{y}{/tex}\xa0= qPutting value of p and q in this we get,x = {tex}\\frac{1}{2}{/tex}and y = {tex}\\frac{1}{2}{/tex} | |

Show that 5 root 6 is an irrational number |

Answer» *Anish jha*Bhai tu itna he intelligent hai to tu teacher ban jaa...Aur zara khud shut ho ja uske baad kisi aur ko krna?? Waise hame sabki help karni chahiye itna ghamand accha nahi hota hai ki kisi ko rula do Hii Sakshi Agarwal , sorry my first solution is wrong and you I again solved that question which is absolutely correct Let 5√6 is an rational no. Where a and b are integers and b is not equal to 0 such that 5√6=a/bThen we get √6=a/5b Since, 5,a,and b are integers a/5b is rational so √6 is rational. This contradiction has arisen due to our wrong assumption . So we conclude that 5√6 is iraational no. And 5√6 =a/b Sorry where a and b are integers and b is not equal to 0 Let 5√6 is an rational no. Where p and q are integers and q is not equal to 0 such that 5√6=p/q we get √2=a/3bSince 3,a,b are integers , a/3b is rational,and so √2 is rational.But this contradicts fact that √2 is irrational. So, we conclude that 5√6 is irrational no. 5√6=p/q ;q is not equal to 0 &P&Q are coprime with each otherP/Q=5√7P-7/q=√5an rational number will never be equal to irrational number so 5√6 is irrational number Just shut your mouth agar itna bhi ni ata to ninth class me jake Beth ja |
